This used to be possible before:

  commit 6d32773e811882f78dbd8c2a39a2b7a9c3cfca7c
  Author: Richard W.M. Jones <rjones at redhat.com>
  Date:   Thu Mar 18 11:15:06 2021 +0000

    tests: Run the tests in parallel.

As far as I know it's no longer possible to run just tests from a
single directory.

However - a bit clumsy - if you know the exact list of tests you want
to run then this works:

$ make -C tests check TESTS=" luks/test-luks.sh luks/test-luks-list.sh luks/test-key-option.sh luks/test-key-option-inspect.sh "
...
make[3]: Entering directory '/home/rjones/d/libguestfs/tests'
SKIP: luks/test-key-option-inspect.sh
PASS: luks/test-luks-list.sh
PASS: luks/test-key-option.sh
PASS: luks/test-luks.sh
